KK-DUALITY FOR SELF-SIMILAR GROUPOID ACTIONS ON GRAPHS
No full textWe extend Nekrashevych’s KK-duality for C∗-algebras of regular, recurrent, contracting self-similar group actions to regular, contracting self-similar groupoid actions on a graph, removing the recurrence condition entirely and generalising from a finite alphabet to a finite graph. More precisely, given a regular and contracting self-similar groupoid (G, E) acting faithfully on a finite directed graph E, we associate two C∗-algebras, O(G, E) and Ô(G, E), to it and prove that they are strongly Morita equivalent to the stable and unstable Ruelle C*-algebras of a Smale space arising from a Wieler solenoid of the self-similar limit space. That these algebras are Spanier-Whitehead dual in KK-theory follows from the general result for Ruelle algebras of irreducible Smale spaces proved by Kaminker, Putnam, and the last author
K-theory for group C*-algebras
No full textThese notes are based on a lecture course given by the first author in the Sedano Winter School on K-theory held in Sedano, Spain, on January 22-27th of 2007. They aim at introducing K-theory of C*-algebras, equivariant K-homology and KK-theory in the context of the Baum-Connes conjectur
[[alternative]]Shape and KK Masses
No full text[[abstract]]我們討論在六維時空模型中，額外維度空間的形狀對現象學的影響。兩個以週期性條件緊緻化的維度可以夾角Θ，此角對Kaluza-Klein態的質量有很大影響。我們特別考慮Θ<<1的情況，大部分的KK態質量會比Θ=90°時大很多，但是有一群KK態的質量會相較下小很多，我們討論這些Light KK態的KK數n1、n2滿足哪些條件，並以一個具體Θ為例找出最輕的一些KK態，這些態通常具有蠻大的KK數。如果在Universal Extra Dimension模型中來討論，KK數守恆會造成許多Light KK態無法衰變，而形成穩定粒子，這些粒子可能成為黑物質。

KEBERADAAN INDUSTRI PT. KEONG NUSANTARA ABADI (WONG COCO) TERHADAP PERUBAHAN SOSIAL DAN EKONOMI MASYARAKAT DI DESA MOJOAYU KECAMATAN PLEMAHAN KABUPATEN KEDIRI
No full textAbstrakIndustri PT. Keong Nusantara Abadi (Wong Coco) berada di Desa Mojoayu Kecamatan Plemahan Kabupaten Kediri. Keberadaan industri tersebut menjadi salah satu faktor perubahan kondisi masyarakat terutama kondisi sosial dan ekonomi. Perubahan kondisi sosial yang muncul antara lain yaitu perubahan sikap, hubungan sosial dan kontribusi industri terhadap perkembangan desa. Perubahan ekonomi yang terjadi yaitu perub?ahan pendapatan dan pengeluaran masyarakat desa selama satu bulan. Tujuan dari penelitian ini adalah mengetahui karakteristik industri, perubahan kondisi sosial dan ekonomi masyarakat dengan keberadaan industri pengolahan lidah buaya.Jenis penelitian ini adalah penelitian survey dengan menggunakan metode penelitian kuantitatif. Penelitian dilakukan di Desa Mojoayu Kecamatan Plemahan Kabupaten Kediri. Responden dalam penelitian ini antara lain yaitu kepala bidang pertanian, kepala Human Resource Department (HRD), PT. Keong Nusantara Abadi (Wong Coco) dan 100 Kepala Keluarga (KK) masyarakat Desa Mojoayu dengan menggunakan simple random sampling. Teknik analisis data dalam penelitian ini yaitu deskriptif persentase.Hasil penelitian menunjukkan bahwa karakteristik industri pengolahan lidah buaya dilihat dari alasan pemilihan lokasi dan kerjasama dengan masyarakat. Sikap masyarakat mengalami perubahan dengan jumlah 50 KK atau 50%, hubungan sosial masyarakat mengalami perubahan dengan jumlah 69 KK atau 69%, kontribusi industri pengolahan lidah buaya terhadap perkembangan desa dalam kategori kurang aktif dinyatakan dengan jumlah 56 KK atau 56 %. Pendapatan dan pengeluaran masyarakat mengalami perubahan relatif kecil dinyatakan dengan jumlah pendapatan 45% atau 45 KK dan pengeluaran 46% atau 46 KK. Keberadaan industri pengolahan lidah buaya menjadi salah satu faktor yang memberikan perubahan kondisi sosial dan ekonomi masyarakat di Desa Mojoayu Kecamatan Plemahan Kabupaten Kediri.Kata Kunci: Industri, kondisi sosial, kondisi ekonomi, lidah buay

No full textMidpalatal suture maturation staging using cone beam computed tomography in patients aged between 9 to 21 years
No full textMidpalatal suture was analysed with cone beam computed tomography to identify its maturation with respect to age and maxillary-complex growth in 72 patients 9- to 21-year-old. Maxillary-complex was divided in premaxillary, maxillary, and palatine segment. Interdigitation and ossification of midpalatal suture, its density relative to hard tissues and soft tissues, and midpalatal suture density ratio were measured for each segment. Correlation of each parameter with age and maxillary-complex length was analysed, and classification trees were developed for staging parameters. Midpalatal suture maturation stages (MPSMS, from A to E) were applied to assess relationship with age and maxillary-complex length. Regarding age, ossification increased in maxillary segment of males (rS = 0.39, p = 0.032), while suture density relative to soft tissues increased in maxillary (rS = 0.37, p = 0.042) and palatine segments (rS = 0.41, p = 0.027) of males and in palatine segment of females (rS = 0.32, p = 0.041). In males, suture density relative to soft tissues discriminated two age-stages (p = 0.024), and the same parameter (p = 0.023) paired with ossification (p = 0.027) discriminated two length-stages. MPSMS identified length-differences between stage A and B in females (p = 0.001). Midpalatal-suture ossification and its density relative to soft tissues showed some relationship with age and maxillary-complex length, especially in males. However, challenging staging and limitations in the imaging method may limit clinical applications
